Please note the screen shot.

Trust Wallet is a decentralized wallet.
It works differently than those wallets that are on popular exchanges.
There will be a fee for every transaction submitted to a cryptocurrency network.
The fee is set by the network, and the wallet just follows these specific rules.
Here is an article explaining more about Network Fees:

In your case, you are trying to send an BEP2 token that resides on the BNB Chain.
You need to have some BNB first on your wallet to pay the miners validating the transaction.
